4 Claims. (01. 155-496) This invention relates to improvements in acomposite metal and wood furniture structure, and more particularly toan improved arrangement for securing a wooden leg member to a metalframe member for supporting a wood chair seat or the like.

The present application is a division of my application Serial No.402,912, filed July 18, 1941.

The object of the present invention is to provide a composite metal andWood structure for chairs or the like, which is comparatively cheap tomanufacture and assemble, and wherein a wooden leg member may be rigidlysecured to a horizontal flanged frame member made of metal, which framemember is also adapted to support a wooden cover, such as a chair seat,table top, or the like. y I

Th advantages of the invention will appear more clearly as I proceedwith my specification.

In the drawing-- Figure 1 is a view of a chair structure in accordancewith my invention;

Figure 2 is an enlarged detail sectional view of the chair seat taken online 2-2 of Figure 1;

Figure 3 is a detail section in horizontal plane taken on line 33 ofFigure 2; and

Figure 4 is a detail section in a vertical plane taken on line 44 ofFigure 2.

In the embodiment illustrated in the drawing, my invention is shown asapplied to a chair, including an upright open metal frame 26 having atop horizontal rail 2| and upright side rails 22, defining the chairback. The side rails 22 are prolonged below the seat, indicatedgenerally at A, to constitute the back legs of the chair. The chair backrails as shown are preferably made of drawn tubular metal.

The seat A includes a metal seat frame 23, herein consisting of channelmetal construction, with upper and lower flanges 25 and 26 extendinginwardly therefrom. The flanges 25 and 26 have reversely turned uprightlips 25l and 26!, respectively, along their inner extremities, as shownin Figures 2 and 3. Said seat frame may extend substantiallycontinuously around the seat A, as shown, and include a front railsection 24, side rail sections 25a, 25a, and a back rail 26a, arrangedto support a seat member 21 made of wood.

In the form shown, the seat member 21 bears at its margins upon themetal seat frame 23, to which is rigidly secured in a mannerheareinafter described. It also extends at its edges beyond the limitsof the metal seat frame so as to prevent the legs of the occupant of thechair from coming into contact with saidmetal frame.

The front legs of. the chairarev indicatedat 36, 30. These are likewisemade ofwood and are disposed at the top in the front .anglesof the metalframe 23. Each of saidlegs is formed with upwardly facing shoulders 3l,QL adjacent itS upper end, adapted to fitunder the adjacent lowerflanges 26, 26 of said metal frame 23, to afford supporting engagementfor the latte r.

The legs are therefore adapted toabsorb the full load thrust from themetal framev The means for securing each of the front l gs 30 to theseat frame 23 inone of thefront angles thereof is shown in detail inFigures 2,,3 and 4, and includes an upright angle plate 3.3 having oneflange engaging aninner face ofeach leg at its top, and the otherflangeehgagingthe rear face of said leg and being secured thereto by twopairs of vertically spaced boltsfl l jfi, which extend outwardly throughsaid leg at right angles to each other. The outer ends of each pair ofbolts 36, 36 are threaded respectively into spanner plates, 31, 31,which are provided with properly spaced threaded holes for this purpose.These spanner plates are each mounted in upright position with theirupper and lower ends bearing against the inner faces of the upright lips25l and 2%! of the front and rear side frame rails 24 and 2511,respectively, as clearly shown in Figure 4. In this manner the legs aresecured with their shoulders 3| in supporting engage ment beneath themetal seat frame 23 so as to provide an especially rigid connectionbetween the wooden and metal parts, as is required in a structure ofthis kind.

The seat member 21 is secured to the open chair frame 23 by means ofangle clips 38 (see Figure 2) placed at difierent points along saidframe, and having hooked engagement with the bottom of the lip 25! ofupper flange 25 of said supporting frame, and being connected by screws39 to the bottom of the wooden seat member 21. As many of said angleclips may be used as are necessary to provide a rigid connection betweenthe wooden seat 21 and the open seat frame 23.

From the above description, it will now be understood that the flangedopen seat frame 23, the wooden seat member 21, and the pairs ofthroughbolts 34, 35, arranged at right angles to each other, allco-operate to provide an especially simple and yet rigid connectingmeans for the front legs of the chair.

Although I have shown and described my invention as applied to a chair,it will be understood that it is not necessarily limited to such use,but may be applied to composite wood and metal tables, or likestructures. Moreover, it will be understood that modifications of theconnecting means may be made without departing from the spirit and scopeof my invention as defined in the appended claims.

I claim:

1. A composite metal and wood furniture structure including a horizontalmetal channel frame with a vertical web and top and bottom flanges eachhaving opposed upright lips spaced from said vertical web, a wood topmember supported on said channel frame, wood less depending from andfixed against the top and bottom flanges of said channel frame withinthe corners thereof, and means for securing said wood legs to saidchannel frame, comprisin pairs of vertically spaced bolts extending atright angles to each other and taking through said leg, and spannerclips, one for each pair of bolts having their ends bearing against theupright lips of said channel frame and threaded to receive said bolts.

'2.-'A composite metal and wood furniture structure including ahorizontal metal channel frame with a vertical web and top and bottomflanges each having opposed upright lips spaced from said vertical web,a wood top member supported on said channel frame, wood legs dependingfrom and fixed against the top and bottom flanges of said channel framewithin the corners thereof, and means for securing said wood legs tosaid channel frame, comprising an angle plate having its flangesengaging an inner and rear face of the leg, pairs of vertically spacedbolts extending at right angles to each other and taking through saidrespective flanges and through said leg, and spanner clips, one for eachpair of bolts having their ends bearing against the upright lips of saidchannel frame and threaded to receive said bolts.

3. A composite metal and wood furniture structure including a horizontalmetal channel frame with a vertical web and top and bottom flanges eachhaving opposed upright lips spaced from said vertical web, a wood topmember supported on said channel frame, wood legs depending from andfixed against the top and bottom flanges of said channel frame withinthe corners thereof, said wood legs each having an. upwardly facingshoulder for engaging the bottom flanges of said channel frame insupporting relation, and means for securing said wood legs to saidchannel frame comprising pairs of vertically spaced bolts extending atright angles to each other and taking through said leg, and spannerclips, one for each pair of bolts, having their ends bearing against theupright lips of said channel frame and threaded to receive said bolts.

4. A composite metal and wood furniture structure including a horizontalmetal channel frame with a vertical web and top and bottom flanges eachhaving opposed upright lips spaced from said vertical web, a wood topmember supported on said channel frame, wood legs depending from andfixed against the top and bottom flanges of said channel frame withinthe corners thereof, and means for securing said wood legs to saidchannel frame comprising pairs of vertically spaced bolts extending atright angles to each other and taking through said leg, and spannerclips, one for each pair of bolts, having their ends bearing against theupright lips of said channel frame and threaded to receive said bolts,said leg having an upwardly facing shoulder abutting the bottom surfaceof said metal channel frame in supporting relation, and clips connectedto the bottom of said top member and engaged with the upper lip Of saidmetal channel frame.
